Watering trough for pigs - has wall mounted water inlets at rear and central float to ensure constant level

摘要

The watering trough is made from cast aluminium, protected by an anti-corrosion coating. It is wall mounted (5,8,14) and used for pigs and similar animals. At the rear is a cast-in manifold, giving a selection (6,9,10,13,15) of water inlets, vertical or horizontal, available either side or top or bottom. Those not used are blanked off by plugs. The water is contained in a covered bowl (1,2) fed from below (12) and passing through a pipe (11). This is controlled by a float to give a constant water pressure. The bottom of the bowl has a depression (3) to collect dirt, cleaned out by removing a plug.
